Cut-Away View of Mounting Bosses
Note: If longer screws are substituted, care should be taken to prevent piercing the roof, and be
sure that pan head screws and washers are used to prevent screws from pulling through the
screw boss. Eight screws must be used and secured to solid structure when mounting.
Antenna Information
The following are a few points to consider in regards to TV reception in a mobile application.
Generally in a mobile application, the lower channels are the most difficult to receive due to the
size of the antenna needed to receive the signal.
When the antennas are inside the vehicle, the TV signal can be obstructed by the outside metal
of the vehicle. This will diminish UHF performance and may eliminate VHF reception altogether.
VHF channels are 2-13 and UHF channels are 14-69.
Depending on the location of the antenna and the direction of the vehicle, some VHF signal may
be received.
